Abstract
The utility model belongs to the technical field of the wind power generation technique and specifically relates to a fan blade of wind -driven generator, including a plurality of groups blade, the cylinder structure of blade is the semicircle type, there is a set of parallel arrangement's fin the inboard of blade, the outside of blade is the smooth surface. Beneficial effect: 1 the utility model discloses in fin through set up a set of parallel arrangement on fan blade, therefore can increase the amount of wind of storing effectively in the blade, increase the air output of fan, improve fan efficiency. 2 the utility model discloses in through fire -retardant layer of coating and corrosion -resistant layer on blade and fin, can effectively improve the corrosion -resistant ability of fan blade and fin, prolong the life of fan blade and fin.
Description
Technical field
The utility model relates to technical field of wind power generation, especially a kind of fan blade of wind-driven generator.
Background technique
Wind-power electricity generation is the effective way realizing energy-saving and emission-reduction.Fan blade is one of core component of blower fan unit equipment.Meanwhile, the load that blower fan is main is all rotated windward by blade and produces.So the structure of fan blade directly determines the overall performance of blower fan.Fan blade is most important parts of wind-driven generator, not only wants smooth operation, also should have larger power performance, starts wind driven generator rotation, and be issued to the rotating speed needed for rated power in minimum wind force intensity when lower wind speed.
But the blade of existing wind-driven generator also exists following technical deficiency: 1, power character is inadequate, can not start wind driven generator rotation when lower wind speed, under minimum wind force intensity, rated power is unstable; 2, the utilization ratio of blade to wind-force is low.
Summary of the invention
The purpose of this utility model is: overcome deficiency of the prior art, provides the fan blade of the wind-driven generator that a kind of wind energy utilization is high, power character is strong.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A fan blade for wind-driven generator, comprises some groups of blades, and the cylindrical structure of described blade is semi-circular, and there is one group of fin arranged in parallel the inner side of described blade, and the outside of described blade is smooth surface.
Further, comprise upper and lower two groups of blades, at right angle setting between described upper and lower two groups of blades.
Further, described fin arranges in longitudinal S type on blade.
Further, described blade and fin scribble flame retardant coating, outside described flame retardant coating, scribble one deck corrosion-resistant finishes.
Further, the height of described fin is 5-8cm.
Further, described blade comprises the S-type blade of two occlusion installations.
The beneficial effect of employing the technical solution of the utility model is:
1, in the utility model by arranging one group of fin arranged in parallel on fan blade, thus can effectively increase the air quantity stored in blade, increase the air output of blower fan, improve fan efficiency.
2, pass through in the utility model to apply flame-retardant layer and anti-corrosion layer on blade and fin, effectively can improve the corrosion resistance of fan blade and fin, extend the working life of fan blade and fin.
Accompanying drawing explanation

Fig. 2 is the structural representation of blade;
In figure: 1 is blade, 2 is fin, and 3 is flame retardant coating, and 4 is corrosion-resistant finishes
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, plant the fan blade of wind-driven generator, comprise some groups of blades 1, the cylindrical structure of described blade 1 is semi-circular, and there is one group of fin 2 arranged in parallel the inner side of described blade 1, and the outside of described blade 1 is smooth surface.
Preferably, comprise upper and lower two groups of blades 1, at right angle setting between described upper and lower two groups of blades 1.Adopt this structure, effectively can increase the area of contact of wind and blade, improve the air quantity that blade stores, improve the working efficiency of blade.
Preferably, described fin 2 arranges in longitudinal S type on blade.Adopt this structure, effectively can increase the area of contact of wind and blade, improve the air quantity that blade stores, improve the working efficiency of blade.
Preferably, as shown in Figure 2, described blade 1 and fin 2 scribble flame retardant coating 3, outside described flame retardant coating 3, scribble one deck corrosion-resistant finishes 4.Adopt this structure, flame retardant property and the decay resistance of fan blade and fin can be improved, improve the physical life of fan blade and fin, reduce user cost.
Preferably, the height of described fin 2 is 5-8cm.
Preferably, often organize blade 1 and comprise the S-type blade of two occlusion installations.Adopt this structure, the air output of fan blade can be improved, improve wind-powered electricity generation transfer capability.
The above; be only embodiment of the present utility model; protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
